摘要
Abstract
In this article, it used two kinds of welding process (GTAW+SMAW and GTAW)to carry out butt welding for A106B pipeline steel, selecting 2.5 mm solid core welding wire of ER70S-G, without heat treatment for test sample before and after welding. Through polarization curve measurement for welded joint weld, HAZ and base metal, the corrosion behavior of welded joints various regions under two welding process were studied. The results showed that the corrosion resistance of two kinds of welded joints various regions are as follows:the base metal>HAZ>weld.关键词
